IMPROVEMENT IN PLOWING AND HARROWING MACHINES.

Specification forming part of Letters Patent No. 9',i69, dated January 4, LtL

To LZZ whom it may concern.-

Be it known that I, ARTHUR CUNNINGHAM, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and Improved Plowing and Harrowing Machine; and

Y Ido hereby declare that the following is a full.

clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication.

This invention relates to improvements in machines for plowing and harrowing; and it consists in certain peculiar arrangements of connecting and operating` devices, whereby a common plow and harrow are connected to a truck adapted for the operator to ride on in away by which he may govern the plow and harrow as required. The said plow and harr'ow are adj ustably connected to the frame of the truck, so as to vary their action.

Figure l is a side elevation of my improved machine, and Fig. 2 is a planview of the same.

Similar letters of reference indicate corresponding parts.

A is the platform of atruck, mounted on two wheels, B, and provided with aseat, G, for the attendant; also, with a tongue and bitching apparatus for attaching a team. At the front end of this platform is astrong beam, D, projecting from one side, either right or left, as the plow is required to turn; or there ma-y be two beams, one attached to the ltop and the other to the bottom of the platform. These beams D supporta draw-rod, E', in a vertical position in the plates E, )reject-ing rearward from the beams, to which rod the plow-beam O, and extending rearward near to the seat,

for operation by the attendant while sitting thereon".

P is ahool; rising up from the platform for engaging the lever N when pressed down, `and holding it there to suspend the plow above the ground when not required to work. j This lever also serves to raise it at any time to carry it over obstructions or for other purposes.

handles upon a rod, Q, stretching between and supported by the perforated bars R, attached to the rounded end S of a bar, T, attached to the rear end of the frame, and projecting at the side thereof'.v These bars are connected to the said rounded part of the bar, so as to be adj usted to or from each 4other and to oscillate thereon. They rise up against the handles of the plow at the outsirles, taking them between and holding them against lateral movement while the rod Q holds them up. This rod may be changed from one set of holes to another, to support the handles higher or lower, or for plow-handles of different heights. The plow is connected at the rear by a chain, U, with another projecting beam, V, so that bybacking up the truck the plow can be drawn back to disengage it from roots, large stones, or other obstructions which it cannot overturn. The front projecting beam, D, supports a vertical guide, W, to run in the furrow against the vertical wall thereof 'or landside, to prevent the plow from running too far to land. This guide is capable of sliding up and down through a suitable guide on the beam D, and the upper end is connected to one end of a lever, X, also supported in the post L. The other end is connected by a rod, Y, to alever, Z, connected at Z under the frame of the truck. The other end rises vertically through the platform, and is provided with a foot-rest, Z2, for the operator to press it down to raise the guide ont of `the furrow when the machine is turned.

with this foot-rest and holding it down when the machine is to be drawn from one field to vided with a runner, Z", shaped to prevent catching in the earth.

around a post, Xt, projectingdownward from the beam V by a chain, Xi. This post sup ports a clearingplate, y', a suitable distance above the ground, through which' the harrowteeth pass, and by which they are cleared of the grass, roots, and other collections by raising the harrow up when required. This is done by the hand-lever Y2, supported on the The rear end of the plow is supported by the"y Z3 is a button on the platform for engaging another or over the road. The guide is pro#` X is a harrow suspended from the lever X2 posts Y, and connected to the lever Xi bythe rod Y4.

Y5 is a post near the drivers seat, with a notch in the top, into which the free end of the lever Y2 is placed, to hold the harrow down into working position.

This harrow may be of any preferred construction, and of any size or number of teeth. I prefer, however, to arrange it so that it will work over a space somewhat broader than the' adjustable block F, substantially as specified.
